How do I cascade X-Desks?
Linking the "X-Desk Out" connector of your second unit into the "X-Desk In" of your primary unit will cascade the Mix Bus, Cue Bus, Solo, and FX 1 & 2 signals. You can link multiple X-Desks together to create a larger mixer. The Mix bus of the second unit is fed post insert and gain trim (so it could be used for sub-group compression, e.g. drums) into pre-insert and gain trim on the primary desk.
